OIL-STOVE.

SPECIFICATION forming' part of Letters Patent NO. 482,539, datedSeptember 13, 1892. Application iilecl April 3, 1890. Serial No.346,402.V (No model.)

To all whom. it nfl/ay concern:

Be it known that we, VILLIAM M. BOWMAN and ELMER F. SHAW, citizens ofthe United States, residing at Plymouth, in the county of Plymouth andState of Massachusetts, have invented a new and useful Improvement inOil-Stoves, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingto a part of this specification, in explaining` its nature.

The invention is an improvement in oilstoves, and relates especially tothe burner, its form of construction, and manner of securing it to thereservoir.

l-Ieretofore burners of lamp-stoves have been made of thin sheetmetalstruck up or otherwise formed and comprising a number of pieces, one ormore of which form a houszo ing for the wick-raiser, which hasinvariably been placed upon the side of the burner and outside thereservoir-space. Thisconstruction is relatively expensive and is notdesirable because of the many joints, many of z5 which require solderand which renders the burner liable to fall apart or become useless bythe melting of the solder. By our invention we locate the wick-raiser ina chamber or box opening directly into thereservoir,iustead 3o ofplacing it in a housing upon the side of the burner. This enables us touse as a section of the burner a box or housing of cast metal and in oneor two sections, as may be desired. It also enables us to attach andhold the sheetmetal portion of the burner to the reservoir in a way toprevent it from being injured, damaged, or made inoperative by heat, asalthough solder may be employed in perfecting some of the jointstheburner is so constructed that 4o if the solder be melted it will notfall apart.

The invention further relates to various details of construction, all ofwhich will hereinafter be described.

Referring to the drawings, Figure l is a View in perspective of theburner, a portion of the top plate of the oil-reservoir being alsoshown. Fig. 2 is a View in perspective of a portion of the burner toshow it in section and to illustrate its relation to the top plate ofthe reser- 5o voir. Fig. 3 is a view in plan thereof. Fig. 4 is atransverse sectional view of a modified form of the invention, to whichreference is hereinafter made.

We have shown in the drawings only a portion of the top plate of themet-al reservoir, and A represents such plate.

B is a box, of cast-iron or other cast metal, having its sides Z9 b andends h2 b3 integral. Its topb* may be integral with the remainder of thebox or it may be formed by a separate 6o cap-plate b5, as indicated inFig. et. Its base or lower edge b may be integral with the top plate A,as represented in Fig. et, or may be united thereto, as represented inFig. 2, by a common plaster joint, the plate A having a cup-recess toreceive the lower edge of the box and plaster, or in any other desiredWay. The box has in its top a long narrow slit c, which extends,preferably, the full length of the box and which is also preferablynearer 7o one side than the other of the box, whereby there is provideda space or chamber c of sufficient size to receive the wick-raiser shaftc2 and wick-raisers c3, carried thereby.

Extending through the slit c of the top of the box is a flattenedwick-tube c4. This wicktube is made of sheet metal of a size to tit theslit c. It has a passage c5 for the wick. It preferably is made of twosections or pieces of sheet metal c6 c7, which overlap at their 8o endsc8 (see Fig. 3) and which overlapped sections extend into the box-slitand are held from spreading apart or opening by the box. There is formedin each side of the Wick-tube above the box-top an outwardextending beada9, which rest-s upon the top of the box. The plate cG of the wick-tubeis made longer than the plate c7 and extends into the box space orcavity below the line of the wick-raisers. The plate c7 does not extendto the wick-raisers, 9o but is bent at om upon the under surface of thetop of the box. (See Figs. 2 and et.) This locks the wick-tube to thebox, the beads c acting as stops to prevent the wick-tube from beingforced into the box farther than is desired and the bent end c10 actingto prevent the wick-tube from being drawn from the box, while the endsc5 held by the top of the box prevent the two parts of the tube fromseparating, or, in other words, hold them firmly ro) together. Thewick-tube of course bears proper operative relation to the wick-raisers,

and the lower section en of the plate c6 acts as a yielding or springplate for holding the Wick in the boxin operative or proper relation tothe Wck-raisers, there being a sufficient amount of give or yield tothis plate to permit this to take place. Ve prefer, also, that thesection c11 be of sufficient width to permit its edges to be bent andreturn slightly to forln guides cl2 for the wick. XVhere the box isconstructed as represented in Fig. 4 the top is united to the sides byplaster joint or in any other desired way. It will be seen that by thisconstruction the box cavity or space opens directly into the chamber ofthe oil reservoir or tank and that the wick-raiser is contained in saidspace; also, by using the casting B an economy in the cost ofmanufacture is obtained, While greater safety and durability areprovided.

Having thus fully described our invention, we claim and desire to secureby Letters Patent of the United Statesl. In oil-stoves, a metal box Bupon the top plate of the reservoir or tank of the stove, having a slitor recess through its top for receiving the Wick-tube and a chamber01""space on one side only for holding the wick-raiser, substantially asdescribed.

2. A burner for oil-stoves, comprisinga castmetal box B, the sides andends of which are integral, a slit through the top near one side,forming an opening for the reception of the wick-tube, the saidwick-tube, and the shaft and wick-raisers contained in said box at oneside of the Wick only, as and for the purposes described.

3. A burner for oil-stoves, comprising a box of cast metal the sides andends of which are integral and which has along opening` through its toplocated nearer one side of the box than the other, a wick-tube insertedin said slit and having one side extending downward into the cavity ofthe box, and a wick-raiser shaft and raisers thereon on the other sideof said downwardly-extending section and in the cavity of said box, asand for the purposes described.

fi. In a burner for oil-stoves, the box B, having the integral sides andends and provided with a long opening through its top near one side ofthe box, a Wick-tube inserted in said opening, made of two pieces,theedges of which overlap, each of which has a rib C9 and one of whichsections extends downwardly into the cavity of the boxl and bearsagainst its side and the other of Which sections has its lower edgefolded upon the under surface of the top ofv the box, a Wick-raisershaft in the cavity of said box, and wick-raisers thereon, as and forthe purposes described.
